hello Juantana,Well I finally bit the bullet and put down a deposit on the 10KW lithium ion pack. Gonna try to install ourselves and Ill do as others have here and document the process. While I am waiting for the pack to be ready, I have a few questions for the folks that have done the upgrade: 1) how hard was the install, and how hard is the Sevcon controller to remove? The charger looks simple but the controller seems in the middle under alot of metal structure. 2) Are there any charging tips or tips in general for cold weather? Will the pack charge under 32 degrees? Mine will be used in the mountains of WV, very deep terrain and it does get pretty cold in winter. 3) are there any maintenance tips and what range do you guys with lithium keep the pack in? Ive been reading that lithium ion batteries like to be around 50-60 %, was thinking 20-80% is a good range to try to keep them in unless you need that extra 20% for something - similar to what they recommend for Tesla or other EV cars. Any info you guys can share is great and Ill post more thru the process too.
I have never had any issues with stalling and I am still loving the pack - the guy at Voltronix emailed me a new profile to load into the BMS, and I never again had that drastic drop on the power meter again -seems the old profile was not 100% correct and they have fixed it it seems. These Li packs dont even drop as much range in winter as the old lead acid ones did - during Covid I took daily ATV riders and could do the whole 40-50, miles in our 10,000 acres "subdivision" - highly recommend the upgrade!hello Juantana,
just curious how your new pack is doing? Also, have you tested it going up very steep inclines yet? Just curious if the Ranger cuts out / stalls like the lead acid batteries do?
I just ordered the largest pack and looking forward to getting installed in one of my machines.
